Introduction: An inverted papilloma is a benign tumor that is found in the nasal cavity or paranasal sinuses. Inverted papilloma accounts for approximately 0.5 to 2.0% of all nasal tumors. While it is considered benign, an inverted papilloma can destroy the surrounding bone. In a small number of cases (5-15%), an inverted papilloma may be found with a squamous cell carcinoma; one such case is reported.

Case report: A 70-year-old male presented with complaints of right-sided nasal blockage, which progressively increased over time and nasal discharge since one and half years with occasional history of epistaxis. On anterior rhinoscopic examination, there was a fleshy polypoidal mass filling the right nasal cavity. Contrast-enhanced computed tomography revealed a soft tissue density mass filling maxillary sinus and posterior choana with mild enhancement. Endoscopic medial maxillectomy was performed with complete removal of mass. Histopathological diagnosis was given as inverted sinonasal papilloma with malignant transformation. The patient was referred to a cancer reference center for treatment and received combined radiotherapy and chemotherapy. Patient was disease free at 6-month follow-up.

Conclusion: An inverted papilloma is a benign tumor with a propensity for malignant change. For these reasons, inverted papilloma should be treated like malignant tumor of the nasal cavity and paranasal sinuses.
